<span>Haemoglobin is a pure substance because it contains only one type of atom. </span>
The word that best fits is frequency. The sentence is The frequency of a wave is a measure of the amount of energy it carries. There is a direct relationship between frequency and energy of a wave. The constant of proportionality is h, Planck's constant. So, Energy = h * frequency. So, the answer is frequency.<span> Although you should know that wavelength is related to frequency and so it is also a measure of the amount of energy and it should also be other valid answer.</span>
Answer:
Proton acceptor → Bronsted-Lowry Base
Provides OH⁻ in water → Arrhenius base
Electron pair donor → Lewis base
Explanation:
We split the references:
Lewis Base
Provides H in water
Bronsted-Lowry Base
Provides OH⁻ in water
Arrhenius base
Proton donor
Proton acceptor
Electron pair donor
Electron pair acceptor
The Bronsted-Lowry theory states that:
- An acid donates protons
- A base recieves protons
The Arrhenius theory states that:
- An acid increases the [H⁺] in aqueous solutions
- A base increases the [OH⁻] in aqueous solutions
The Lewis theory states that:
Acid is the one that accepts a pair of e⁻
Base is the one that donates a pair of e⁻
